Question Paper
Describe the types of treatment units in primary and secondary treatment of wastewater.
Describe in brief activated sludge process design. What are the various limitations of ASP process? Explain the various modifications of the process.
Noise characteristics are same as sound characteristics. Explain.
Draw the decibel scale to show various sound pressure levels.
Explain the role of lead and high transmission loss ceilings for control of noise.
Discuss the various zones of pollution developed in a river system after a polluted stream is added to the river.
10 million litres of sewage of a town is to be discharged into a river stream having flow of 250 l/s. The BOD of the sewage and river water is 220 mg/l and 5 mg/l respectively. Find the BOD of the river immediately after mixing.
What should be the required percentage treatment of the sewage, if the river water BOD cannot exceed 15 mg/l
Describe the various flue gas desulphurization processes.
Discuss the various control systems available for gaseous pollution control.
What are the various factors influencing the action of disinfectants
Differentiate between dual media and multimedia filters.
Write in brief the effect of pollution on rivers.
Explain the various methods to remove taste and odour from water.
What is Break-point chlorination? What is residual free chlorine?
Explain the process of biofiltration.
Calculate the quantity of sludge produced per day in clarifier having moisture content of 95%. The clarifier removes 60% of incoming solids. Inflow to the clarifier is 200 m^3/hr with 300 ppm of suspended solids. Assume specific gravity of sludge as 1.02.
